The data output from the host computer passes through the control board’s interface then is stored in

RAM by the CPU.

Next, the CPU reads the data stored in RAM and edits it according to the program stored in ROM.

When editing is completed, the CPU outputs various drive signals to the printer mechanism to execute

printing.

[Description of each component]

a. CPU TMP90C041: CMOS-structured single-chip microcomputer

Performs overall control of the printer.

b. EPROM 27256: 32 Kbytes

Stores the program used for control by CPU.

c. RAM 6264: 8 Kbytes

Is used as the stack area and work area by the CPU and as the data buffer.

d. Serial interface circuit

Transfers serial data with the host computer.

e. Gate array

Performs input, output, and conversion of various signals.

f. Driver

Converts the signals output from the CPU or gate array into drive signals to drive the printer

mechanism.

(2) FEED switch

When this pushbutton switch is pressed once briefly (for 0.5 seconds or less), the paper is fed forward

by one line. When it is held down continuously, the paper is fed forward continuously until the switch

is released.

This operation can be performed while the printer is in either on-line or off-line status.

(3) FEED switch + POWER ON (The FEED switch is held down while the printer is turned on)

A self-test pattern is printed to check the printer’s printing functions. The ROM Version No., DIP switch

settings, interface settings, and characters are printed in sequence.

If the FEED switch is pressed at the time self-test printing is completed, only the printing of the

characters can be repeated.

In the case of auto cutter equipped type printer mechanism (MP342F-24-A and MP341F-24-A), partial

cutting and full cutting will be repeatedly performed after completed character printing.

Fig. 3-15 Sample Printout of the Self-Test Pattern

(When using printer mechanism MP312F-24-A)

(4) ON LINE switch + POWER ON(The ON LINE switch is held down while the printer is turned on)

When this mode is activated, all of the data sent from a personal computer or other connected host will

be printed as hexadecimal codes.

By sending a program you have written to the printer, you can check whether or not the control codes

are being properly received by the printer.

– 15 –

If the final line of data does not fill an entire line, the final line of data will not be printed. That line will

be printed, however, when the ON LINE switch is pressed and the printer enters off-line status. To cancel

this mode, turn off the printer.

Fig. 3-16 Sample Hexadecimal Dump Printout

(When using printer mechanism MP312F-24-A)

(5) FEED switch + ON LINE switch + POWER ON (Turn the power on while holding both the FEED and

ON LINE switches depressed.)

This operation clears the printer buffer. (The buzzer gives two short beeps.)

When DIP switch 1-7 of this board is set to ON (which is the factory presetting), the RAM back-up

function operates to maintain the data in the data buffer, even if the power for the board is shut off due

to power failure, etc.

However, when the board power is shut off for more than 10 hours, the data content will become unstable

and its content could degenerate and become unusable in the worst instances. For this reason, when the

board power is turned off for more than 10 hours, perform the above operation to clear the data in the data

buffer.

Note that the data in the buffer can also be cleared by control code < CAN >.

(6) ON LINE switch + FEED switch (In off-line status, the ON LINE switch is held down while the FEED

switch is pressed)

While these two switches are pressed, the paper is fed forward in units of n/72th inch each.

(7) Indicator Lamps

The seven states described in the following table are indicated by the status of the POWER, ALARM,

and ON LINE lamps.

Printer Status POWER Lamp ALARM Lamp ON LINE Lamp

1 Power is on ON OFF ON

2 On-line status ON OFF ON

3 Off-line status ON OFF OFF

4 Validation enabled ON OFF Flashing

5 Mechanical error ON Flashing OFF

6 CPU error ON ON ON

7 Power is off OFF OFF OFF

– 16 –

a. Mechanical error

During operation of the printer mechanism, if either malfunction listed below is detected, a mechanical

error is regarded as having occurred, the printer mechanism stops operating, and the FAULT signal

assumes “mark” status. To cancel a mechanical error, turn the power off and then back on or press the

ON LINE switch, after the problem is corrected.

[Malfunctions of the printer mechanism]

• Lock-up of the carriage motor

• Malfunction of the timing detector (Timing signals are not generated)

• Signal timing error of the auto cutter

Even while in the status of no RAM back up with DIP SW1-7, the RAM is not cleared when power is

turned OFF. Printing resumes from the line being printed when the mechanism stopped.

b. CPU error

If operation of the CPU hangs up due to external noise or some other reason, the control board stops

operating. To cancel the CPU error state,the printer must be turned off then back on again.

Refer to < ESC > K as to the relation between the dot position and the bit

number. The printer ignores any data bytes over the specified amount al-

lowed in one line.

The printer does not print adjacent dots. When the bit image printing is

finished, the printer automatically returns to the character mode.

For double density bit image printing, dots cannot be printed overlapping

7. DATA STRUCTURE7.1 DTR Mode

This mode is accessed when the DIP switch 3-5 is ON.

Signals are controlled using the DTR line as BUSY flag.

If a control board errors do not occur after the power is turned on, the DTR signal line changes to “SPACE”.

When the host computer confirms that the DTR signal line is set to “SPASE”, the host computer sends the data

text via the RXD signal line to the control board. Also, the control board will set the DTR signal line to

“MARK”, transmission of the data text is stopped. In this instance, data can still be received up until the data

buffer becomes completely full.

When the empty space in the data buffer is increased following printing (when the data in the data buffer is

reduced to 256 bytes or less), the control board sets the DTR signal line to “SPACE”.

[Framing error]

A framing error occurs when SPACE is detected at the stop bit. When a framing error or a vertical parity error

occurs for the data which is received, the printer prints out a “?” mark to indicate that the error occurred.

[Mechanical error]

Immediately after a mechanical error occurs, the control board sets the DTR to “MARK” and then sets the

control board to OFF LINE.

[Paper out]

When the “paper out” detector senses the end of the paper, the printer stops printing after printing a maximum

of two more lines or on feeding the paper. Immediately after a “paper out” condition is detected, the printer

sets to OFF LINE and the DTR changes to “MARK”. (To reset printer after a “paper out”, load paper into the

printer and press the ON LINE switch to set the printer to ON LINE.)

[Compulsion signal]

When pin 6 of the peripheral unit drive circuit connector is set “HIGH”, status bit 7 becomes “1.”

7.2 X-ON/X-OFF Mode

This mode accessed when the DIP switch 3-5 is OFF.

If control board errors do not occur after the power is turned on, the printer outputs an X-ON (DC1 by control

code; 11H by hexadecimal data) signal on the TXD signal line which sends it to the host computer. When the

host computer receives the X-ON signal, the host computer transmits the data to the RXD signal line for the

printer. If data text is not sent from the host computer (even after transmitting the X-ON signal to the host

computer), the printer outputs an X-ON signal at 3 second intervals until the printer receives data.

The printer starts outputting an X-OFF (DC3, 13H) signal when the empty space in the buffer reduces below

256 bytes. When the host computer receives the X-OFF signal, it halts output of data. (however, the control

board can continue receiving data until the buffer becomes completely full.)

Output of the X-ON signal is resumed when the data in the buffer is printed out and drops to below 256 bytes.

[Framing error]

A framing error occurs when SPACE is detected at the stop bit. When a framing error or a vertical parity error

occurs for the data which is received, the printer prints out a “?” mark to indicate that the error occurred.

[Mechanical error]

Mechanical errors are detected when the carriage motor locks and printing stops. After the error occurs, the

control board outputs an X-OFF signal and stops printing. The control board sets the DTR signal to “MARK”

and sets to OFF LINE within five seconds after a mechanical error occurs.

[Paper out]

When the “paper out” detector senses the end of the paper, the printer stops printing after printing a maximum

of two more lines or on feeding the paper. The printer will set the DTR to “MARK” and set the printer to OFF

LINE five seconds after a “paper out”, load a new roll of paper into the printer and press the OFF LINE switch

to set the printer ON LINE.

When pin 6 of the peripheral unit drive circuit connector is set at “HIGH”, status bit 7 becomes “1.”

7.3 STX/ETX Mode

This mode is accessed from whichever DTR mode or X-ON/X-OFF mode.

To set this mode, the data buffer must be empty.

The host computer sends an ENQ code to the control board and acknowledges the printer starus. Then,the host

computer checks if the printer buffer is empty. After the host computer detects that the buffer is empty, a STX

code and data are transmitted. After 1 block of data is transmitted, the host computer sends an ENQ code to

the printer and then receives the printer status and check byte (horizontal parity for the control board).

At this point, the host computer performs a status and horizontal parity check. When the host computer

determines that there was no error, it transmits an ETX code which serves as text end code. After the control

board receives the ETX code, data in the data buffer is printed out. If an error occurs, a CAN code is transmitted

by the host computer. (In this instance, the data which was previously sent to the buffer is cleared, thus, the

host computer must retransmit the same data to the control board.)

A flowchart of this operation is illustrated on the following page.
